ABSTRACT
Energy homeostasis is pivotal for cell fate since metabolic regulation, cell proliferation and death are strongly dependent on the balance between catabolic and anabolic pathways. In particular, metabolic and energetic changes have been observed in cancer cells even before the discovery of oncogenes and tumor suppressors, but have been neglected for a long time. Instead, during the past 20years a renaissance of the study of tumor metabolism has led to a revised and more accurate sight of the metabolic landscape of cancer cells. In this scenario, genetic, biochemical and clinical evidences place mitochondria as key actors in cancer metabolic restructuring, not only because there are energy and biosynthetic intermediates manufacturers, but also because occurrence of mutations in metabolic enzymes encoded by both nuclear and mitochondrial DNA has been associated to different types of cancer. Here we provide an overview of the possible mechanisms modulating mitochondrial energy production and homeostasis in the intriguing scenario of neoplastic cells, focusing on the double-edged role of 5'-AMP activated protein kinase in cancer metabolism. This article is part of a Special Issue entitled Mitochondria in Cancer, edited by Giuseppe Gasparre, Rodrigue Rossignol and Pierre Sonveaux.
